SPECIFICATION forming part of Letters Patent No. 507,647, dated October 31, 1893.

Application filed October 6, 1892- To all whom it may concern Be it known that I, GEORGE CARNELL, a citizen of the United States, residing at Philadelphia, in the'county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Brick-lvlold-sandin g Machines, of which the following is a specifiation, reference being bad therein to the accompanying drawings.

This invention relates to certain new and useful improvements in brick mold sanding machines, and it has for its objects among others to provide a simplified yet efficient machine by which the molds will be manipulated so as to sand them without waste of sand or loss of time, and this with the minimum amount of labor on the part of the attendant.

Other objects and the advantages of the invention will hereinafter appear and the novel features thereof will be specifically defined by the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the let'- ters of reference marked thereon, formapart of this specification, and in which Figure 1 is a plan view of myimproved machine. Fig.2 is a rear end view thereof. Fig. 3 shows in perspective the mold-holding arm and its supporting or holding lug detached from the machine. Fig. 4 is aside elevation. Fig. 5 is a vertical longitudinal section through the machine.

Like letters of reference indicate like parts throughout the several views. 7

Referring now to the details of the draws ings by letter, A designates the frame-work of the machine of any suitable form of construction, of wood, or metal, ora combination of these two materials, constructed to support the operating parts of the machine, and A is a trough or other suitable receptacle supported upon the frame-work beneath the sanding devices in such a position as to catch any sand that may be scattered or thrown over the sides thereof during the operation of sanding the molds in the manner which will soon be explained.

B is a short horizontal shaft journaled in suitable bearings on the frame at a side extension thereof as seen in Figs. 1 and 2, and upon this shaft is a belt pulley B which is designed to receive its motion from any suit- Serial No. 447,989. (No model.)

able source of power, a portion of the belt B being shown in Fig. 4:. This shaft is provided with a clutch B of any suitable or well known construction, by means of which and a suitable lever as B pivoted at b and engaging the movable part of the clutch as seen in Figs. 1 and 2 the machine may be thrown into or out of operation as may be desired. On this shaft is a small gear wheel 1) which meshes with the larger gear wheel I) on a shaft O which is journaled in suitable bearings in the frame beneath the shaft B as seen best in Figs. 2 and at. The gearing may be covered and protected by a suitable shield as seen at b in the different views.

On the shaft 0 is a cam 0' carried bya collar or boss 0 as seen in Figs. 2 and 5 and this cam performs an important function in the operation of the machine as will soon appear. On this shaft 0 are also the arms C preferably though not necessarily, two in number, one near each end,and adj ustably connected with each of these arms is an arm 0 carrying at its free end an anti-friction roller 0' as seen in Figs. 1, 2 and 5 whichis designed to engage the rear end of a mold and force it along at predetermined periods as will soon be explained. The connections between the arms 0 and C are of an adjustable nature as seen in Fig. 5 so that the position of the arm C relatively to the arm C can be varied to adapt the roller to different sized molds, the arm being made longer or shorter as may be required. In this instance I have shown this adjustment as provided for by a set screw 0 "in the one part,the other being provided with a slot 0 as seen in Fig. 5, but other forms of adjustable connection maybe employed.

D is a mold receptacle which may have a capacity for more or less molds as may be desired, and suitable means as spring plates 01 may be employed for keeping the molds true as they descend; the bottom of this mold receptacle is open as shown in Fig. 5 to provide room for the working of the rollers c, suitable end guides d being provided for the support of the molds as seen in Fig. 1.

D are the molds a number ofwhich are shown in the mold receptacle in Fig. 5, resting one upon the other. Others are shown as hav ing been moved along from the said receptacle, one being shown beneath the sand receptacle and another as having been filled with sand andraised and held by the arms which are provided for this purpose.

E is the sand receptacle or box suitably supported above the mold support or platform E upon which the molds are supported as they are forced along. This mold receptacle has an inclined bottom (2 as seen in Fig. 5 so that the sand will flow readily, and E are inclined bars at the top of the sand receptacle upon which the molds are designed to besup' ported when the sand is being emptied therefrom back into the receptacle.

F is a compound curved arm pivoted at one end as atfto the frame of the machine as seen best in Fig. 5, and at its other end it carries a plate or board F as seen in the various views uponwhich the molds are adapted to be received and elevated in a manner which will soon be described. arm at a point where it will be engaged by the cam 0' as seen best in Fig. 5. This arm is guided in its vertical movements by'suitable guides as f, see Figs. 2 and 5.

any snitablemanner at the proper height so as to permit the passage of the molds there beneath; uprights or pillarsf for instance may be employed for this purpose as seen in Fig. 4.

G are castings secured to the frame of the machine at the end as shown in the various views, and having lugs or ears 9 between which are pivoted the arms II, one at each slde ofthe machine. As seen best in Fig. 3, each of these arms consists of abranched vertical portion h the arms of which are designed to engage the bottom of a mold as seen in Figs. l and 5, and a lateral portion 72/ through which the pivot passes, and between the pivot k and the vertical portion of the arm there extends through the lateral portion a setscrew h by the adjustment of which'the arms may be thrown out or in to adaptthem to receive and hold molds of varying sizes.

The operation will be apparent from the foregoing description when taken in connectionwith the annexed drawings. The molds next one to drop; in the further movementare placed in the mold receiver and the -sand receptacle filled with sand. Motion is im-"' parted to the driving mechanism and the cam and co-operating parts are so timed that as its shaft revolves the arms O and O operate to eject the lowest mold from its position at the bottom of the mold receiver andallow the of the partsthis mold is pnshedturther along elevate the forward end of'the arm F Withand another dropped, when the mold'arrives beneath the sand receptacle it is filled with "sand and the parts being properly'timed in their movements as soon as a mold is pushed onto the plate or board F the cam acts to thesaid plate or board and force the mold upward where it is forced between and held by the arms II as shown in Figs. 4 and 5; the

next mold is forced against the bottom of the F is a roller onthis The sand receptacle may be supported in mold held by the said arms and-forces it upward audit is tipped over upon the inclined arms or supports E and the sand emptied into the sand receptacle. The molds are fed to the mold receiver and the operation continues. The screws 7L3 are adjusted in or out and the arms C and C are shortened or lengthened to accommodate boxes of varying sizes.

Modifications in detail may be resorted to without departing from the spirit or scope of the invention or sacrificing any of its advantages.
